This is my minimalistic desktop.
Running Nocturne for Mac to get the black menu bar - items on the menu bar appear when your cursor touches it.
I am running Docker to customize my dock. It allows you to resize, add spaces, make it 3D/2D, etc.
I also use Hyperdock; an application that allows you to resize windows instantly to 1/2 the screen, the lower half, or full screen. It also gives you window previews from the dock.
If you have any questions, just ask.
